Title: Improvements in or relating to cutting devices for copying machines
IPC: B41L7/06
Filed: 1922-12-27
Abstract: 191,043. May, F. Dec. 27, 1921, [Convention date]. Cutting and perforating apparatus. - A cutting-device for a copying-machine comprises a knife 2, on pivoted arms 3 swung into cutting position by a cam, and a co-operating flat twisted knife 1 inclined to the paper and driven by an attached mutilated pinion 5 gearing with a constantly rotating wheel 7. The pinion 5 carries two side teeth 8 at the points where it is mutilated which teeth co-operate with a tooth 10 on a lever 9, provided with slots 14, 15 of different widths mounted on the boss of the wheel 7. Pins 13 of different lengths can be projected through holes in the wheel 7 by a rack and pinion actuated from on rotation of a lever 38 in such a manner that the arm 9 with tooth 10 is turned by a projected pin 13 to initiate the rotation of the gear 5 for half a revolution. The arm 9 is restored to its initial position by a cam 17, which acts on a pin 16 attached to the arm, to axially shift the latter and allow the pin to pass through the slot 14 and a restoring spring 11 to act. To cut off a strip of any length, the pins 13 are put out of action and a pawl 25 is rotated on depression of a rod 27 to place a tooth 23 in contact with the teeth of the wheel 7. The tooth is held in engagement and is afterwards released by a cam slot 29 acting on a pin 30. The knife 1 is locked in its idle position by a detent 31 operated through a lever 32 from the arm 9, and the knife is swung out of the cutting position by a cam 33. In the arrangement shown in Fig. 1, three rotary positions of the lever 38 are provided ; in two of them one or two pins 13 may be projected to out automatically lengths of 23 and 46 cms, and in the third the shaft 27 can be axially shifted to actuate the pawl 25 to cut lengths other than the above. Means are described by which a reciprocating gripper feed for the paper is controlled by a hand-set key which also controls the actuation of the rod 27.

Title: Dental multifunction handpiece
IPC: A61C17/02
Filed: 1972-07-27
Abstract: 1333156 Dental syringes KALTENBACH & VOIGT 27 July 1972 [27 July 1971] 35251/72 Heading A5R A dental syringe for the selective supply of air, water or a spray of air and water from a cannula connected to the tip of the handpiece comprises an air conduit 6 with an associated control valve 8 and a water conduit 7 with an associated control valve 9, the valves 8, 9 being actuated by manipulating means 5, 4 respectively provided on an outer sleeve 2 of the syringe. The air conduit 6 connects through a change-over valve 28 with a branch duct 6a which ends concentrically with conduit 7 at the cannula outlet and conveys air for the air-water spray, and with a further duct 6b through which air passes for air-only supply from the cannula. The valve 28 is initially set to connect air conduit 6 with duct 6b and is actuated by the manipulating means 4 through control lever 12 from which extends a shoulder 17 abutting against the spindle of valve 28. When manipulating means 5 alone is operated, valve 8 is opened to allow passage of air from conduit 6 via duct 6b to outlet 27. When manipulating means 4 is operated alone, valve 9 opens to allow passage of water through conduit 7, and simultaneously valve 28 is operated to put air conduit 6 in communication with duct 6a but valve 8 prevents air flow therethrough. When manipulating means 4, 5 are operated simultaneously, an air-water spray issues from the cannula. A diaphragm pump 43 is arranged in water conduit 7 and is primed by actuation of control lever 12. The valves 8, 28 are arranged co-axially as an assembled component, and the pump 43 and valve 9 are arranged coaxially as a further assembled component, both components being detachably secured in the syringe. Means are provided for selectively heating the air and water supplied through the cannula.

Title: An improved wheel-track gauge for motor vehicles
Filed: 1957-11-12
Abstract: 816,729. Wheel alignment gauges. HAIR, D. W. Nov. 12, 1957 [Dec. 4, 1956], No. 35268/57. Class 106 (2). [Also in Group XX] A wheel tracking gauge for motor vehicles comprises two comparison bars 16 having straight edges 17 and fitted with magnets 20, 21, adapted to adhere to the rims of the steerable wheels of a motor vehicle at spaced points so that the bars 16 are heldi n a horizontal position against the wheels, thus enabling the straight edges 17 to be used for comparison with line markings on the ground or arms 4 forming part of a frame 1 to indicate a particular track setting. As shown, the frame 1, consisting of parallel tubes 2, 2a, 3, 3a, telescopically adjustable, has arms 4 extending parallel to one another and perpendicularly to the tubes 2, 3. The arms 4 carry scales 8, pointers 9 pivoted at 11, and chamfered stubs 7. Two bars 16 having straight edges 17 and adjustable horseshoe magnets 20, 21 are also provided. In operation, the frame 1 is laid on the ground with the arms 4 outside the front wheels of a motor vehicle and the tube 3 touching the front edge of the tyres. The telescopic adjustment of tubes 2, 3 is then used to bring the stubs 7 into contact with the edges of the tyres. One of the pointers 9 is then set against scale 8 to indicate the required toe-in or toe-out, and the other pointer 9 placed at zero, (see Fig. 3). Alternatively, both pointers may be set to half the required toe-in or toe-out. Bars 16 are then clamped to the wheel rims by means of the magnets 20, 21, and the wheel whose pointer 9 was set to zero turned into true straight ahead position, this being gauged by looking along the straight edge 17 and noting any divergency from a centre line 10 marked on the pointer 9. When this has been done, necessary adjustments are made to the tie-rod connections until the other wheel is in correct alignment as determined in a similar manner. If built for use, e.g. in the assembly line of a factory, where the toe-in or toe-out is always constant, the pointers 9 and scales 8 may be dispensed with, and the arms permanently set to the required angle. Alternatively, the frame 1 may consist merely of a bar 3 fixed to the floor, the arms 4 being represented by markings, such as metal strips let into the floor.

Title: Improvements relating to weighing machines
IPC: G01G1/26
Filed: 1928-11-30
Abstract: 301,511. Dockl, J. Dec. 1, 1927, [Convention date]. Loose - weight apparatus.-A non-automatic loose-weight mechanism for a weighing-scale comprises a number of disc-shaped weights each suspended from the lower end of one of a series of coaxial tubes and adapted to be lowered and raised on to and off the weight-pan by the rotation of one ormore. cam cylinders that are provided with partly circular and partly helical slots to co-operate with the upper ends of the tubes. As shown, two series of weights G1 - - G3, G4 - - G7 are adapted to be lowered onto and raised from the weight-plate G5 of a semi-automatic weighing machine by the horizontal rotation of handles H1, H2 respectively. The weights G1 - - G3 are suspended from the flanged lower ends of tubes R1 - - R3, the upper ends of which are slotted to receive supporting plates T. Each plate T is provided with two diametrically opposed rollers P1 that bear upon the upper edge of a rotatable cylinder N1 to which the handle H1 is attached. The rollers of the several weights are equally spaced around the periphery of the cylinder, and upon rotation of the cylinder are guided downwardly into the horizontal parts of slots X1, formed therein, to lower the weights onto the plate. The lowest weight G3 of the series is provided with legs f, the pointed lower ends of which are adapted to engage a groove V in the surface of the weight-plate. The lower series of weights G4 - - G7 are supported through conical hangers O from the flanged ends of an inner series of tubes, the upper ends of which are supported and actuated by a cam cylinder N2 attached to the handle H2. The lowermost weight G7 is positioned on the weight-plate by a conical protuberance SE. The total weight of the loose-weights upon the weight-plate at any time is indicated through two diametrically opposed windows SF in the housing by means of two cylinders Z1, Z2, rotatable with the handles H1, H2 respectively. For a machine in which the weights G1 - - G3 are of five units, and the weights G4 - - G7 of one unit, the cylinder Z1 is marked with two charts similar to that shown in Fig. 11, and the cylinder Z2 is provided with two series of apertures a - - e as shown in Fig. 10.

Title: Control valve
IPC: B60T15/04
Filed: 1963-09-10
Abstract: 1,030,337. Fluid pressure control of brakes. WAGNER ELECTRIC CORPORATION. Sept. 10, 1963 [Feb. 4, 1963], No. 35635/63. Heading F2F. A control valve for use in a fluid pressure braking system having a pair of fluid pressure sources 4, 10 (Fig. 1, not shown) and brake chambers 8, 13, is operable by an applied force to first connect one source 10 to brake chambers 13, this connection causing fluid pressure to act within the valve to connect the second source 4 to the brake chambers 8. Members 70, 63 within the valve form between them an expansible chamber 77. The member 70 is moved downwards by a force acting on plate 80, the extension 72 first abutting the seal 59 of valve 54 to cut off the communication of line 12 (Fig. 1) with atmosphere by way of port 48 and passage 57 and then moving valve 54 from its seat 61 to allow lines 11, 12 to communicate through ports 47, 48. The fluid pressure in chamber 46 passes through passage 76 to act in the expansible chamber to depress piston 63, its lower face 66 first engaging seal 40 in valve 35 to stop communication between port 31 and atmosphere through passage 38 and then depressing valve 35 to connect ports 30 and 31 and hence lines 6 and 7. When sufficient braking force has been applied the forces on piston 70 balance, the piston then rising until valve 54 abuts face 61. Similarly balance of pressures allows valve 35 to rise and abut face 42, " feel " being provided in this manner. Passages 57 and 38 remain closed to atmosphere. Removal of the force on plate 80 allows piston 70 to rise, venting chamber 46 through passage 57 and chamber 77 through passage 76. Piston 63 then rises to exhaust through passage 38 the chamber connected to port 31. The Specification describes two modifications of the valve in which the length of the extension 72 is reduced and acts on the valve 54 through a separate valve member.

Title: Bypass valve mud flaps
IPC: F15B11/16
Filed: 1974-08-13
Abstract: 1447326 Valves BORG-WARNER CORP 13 Aug 1974 [7 Dec 1973] 35640/74 Heading F2V [Also in Divisions F1 and G3] A manually actuated valve 12 controlling flow to a fluid motor 70 has an associated bypass valve 200 responsive to the pressure differential between the inlet 18 and a motor port 20 or 22 of valve 12 and including valve means responsive to motor port pressure to vary the differential at which the bypass valve opens. Bypass valve 200 comprises a landed spool 230 slidable in bore 232 to control flow from pump 202 and supply port 209 to drain port 212 and to main valve inlet 18 via line 214. A chamber 246 to the left of spool 230 is subject to inlet pressure via passage 244 whereas a chamber 292 to the right of the spool is subject via line 126 and ball type shuttle valves 110, 90 to the higher of the pressures in main valve control ports 24, 26. In the neutral position shown of main valve spool 14, these ports communicate with drain passages 28, 30. However when spool 14 is moved towards a work position, e.g. rightwards, land 52 cuts communication between drain 28 and control port 24 whilst notched land 54 opens communication between the latter and motor port 20. Thus the pressure in chamber 292 increases causing a further valve spool 262 to be urged leftwards within bypass spool 230 into a position in which radial ports 278, 284 in the respective spools communicate. A portion of fluid from the supply pump 202 and port 209 can thus flow via ports 284, 278, spool passage 268 and non-return ball 274 into chamber 292 and thence via line 126 to motor port 20 and chamber 74 of fluid motor 70, overcoming the load resistance on the latter. The resulting pressure increase in chamber 292 causes spool 230 to move leftwards thus decreasing the bypass flow to drain port 212 and increasing the pressure differential required to open the bypass valve. As main valve spool 14 moves rightwards, flow to motor port 20 also takes place via inlet 18 and notched land 56. Bypass valve 200 now maintains a constant pressure across the variable control orifice established by main valve 12. Chamber 292 is provided with a relief valve 304. When spool 14 is returned to neutral check valves 32, 34 allow flow through chamber 292 and line 126 &c. to motorport 20 or 22 until control port 24 or 26 is connected to drain 28 or 30 The bypass valve may be associated with additional main valves 114, the shuttle valves 90, 110, 115, 116 ensuring that the chamber 292 is subject to the highest motor port pressure in the system. In a modified bypass valve (200a, Fig. 2 not shown) spool 262 is replaced by a poppet valve (402) slidable within the outer spool (230a) and having a passage (404) which permanently connects supply port (209a) with chamber (292a). When pressure in the latter increases as a result of the main valve being moved towards a work position, poppet 402 moves leftwards to seat against spool (230a) and cut-off flow through additional bypass ports (412) in the spool. In other respects valve (200a) operates in similar manner to valve 200.

Title: Improvements in or relating to the manufacture of fuse elements
IPC: C25D1/04
Filed: 1961-10-04
Abstract: A thin film of gold or gold alloy supported on an insulating layer, e.g. cellulose acetate, is made by plating gold on one side of a thin copper sheet cleaned on both sides electrolytically, floating the plated sheet copper face downwards on an etchant to remove the copper, sliding a glass plate under the floating gold film, and transferring it to a layer of isinglass by which it is bonded to the insulating layer supported under the film.  The coated insulator is then dried by heating to 100  DEG C., and cut into strips for use as fuse elements.  The copper sheet is cleaned with alkali cyanide solution at a high C.D. to clean it, and then at a lower C.D. to polish it.  The etchant to remove the copper may be a bath of ammonium persulphate or ferric chloride. Alternatively the copper may be replaced with silver using AgNO3, and the silver removed with HNO3.

Abstract: 997,118. Gas turbine plant. BROWN, BOVERI & CO. Ltd. Sept. 12, 1963 [Sept. 14, 1962], No. 35963/63. Heading F1G. [Also in Division B1] A gas turbine plant includes distilling means for providing a distillate from a crude liquid, means for vaporizing the distillate, means for feeding the distillate directly to the vaporizing means, and means for feeding the vaporized distillate to the working fluid of the plant at a point before the turbine stage of the plant, the arrangement being such that both the distilling means and the vaporizing means heat the crude liquid and distillate respectively by means of exhaust gas from the turbine stage. A gas turbine plant comprises an air compressor 1 supplying a combustion chamber 2 and turbine 4. Any crude liquid, such as industrial waste water or salt water, is supplied by a pump 7 to a heater 8 where it is heated by exhaust gases from the turbine 4. The liquid passes through throttling valve 9 and some evaporates in evaporator 10 and is then condensed by cool crude liquid flowing through condenser 12. The distillate is forced by pump 13 through heater 14, where it is vaporized and then fed to combustion chamber 2 to increase the output of turbine 4. The vapour may alternatively be introduced before or after chamber 2. Residual liquid from evaporator 10 may be cooled by liquid tapped off through duct 15. A conduit 17 and circulating pump 16 may be provided across heater 8 to raise the inlet temperature of the crude liquid and reduce corrosion. In a modification, Fig. 2 (not shown) the liquid heater is not heated by exhaust gases directly but by distillate tapped off from the vaporizer.
